Research On Optimization Of Pedestrian Evacuation In Arena Based On Three-dimensional Social Force Model

With the development of my country’s economic society,the lives of people in the city are more intensive,and all kinds of public activities in the city are more frequent.When a large number of people concentrate on a certain area,it is easy to crowded with groupual events such as crowded steps.Very extent It is important part of public safety in public safety to harm the people’s lives and property safety.Therefore,research on the evacuation of people in the venue has become a hot spot in the field of evacuation safety.The main research in this research is as follows.First,use the crowd disconnected experimental video of different density of the three regions of the TRACKER Software Venue to see the different densities of the three regions of the corridor.The time,speed,trajectory of each group of experiments,etc.,and carry out evacuation data The analysis is analyzed,and the variations of each evacuation indicator and the evacuation of people in various scenarios have been evacuated,and the three-dimensional social force model is constructed and the fits and venue evacuation optimization provide the basis.Then,for the classic social force model only for two-dimensional plane,it is not applicable to the problem of three-dimensional space with more stairs,etc.,introduces a three-dimensional social force model and fitting its function expression.According to the area of the field,the evacuation experiment in the field,the staircase area and the corridor area is obtained,and each group of experiments simulates each set of experiments in Any Logic,and the evacuation speed and time are obtained,and the three-dimensional social force model is calculated.The self-variable and variable of the anti-gravity psychological repulsive function,the function expression is fitted,and the ideal fit results are achieved,and the three-dimensional social force model applied to the venue is obtained.Finally,according to the characteristics of the venue and personnel,the bottlenecks of the venue and different regions of the venue are identified,and the evacuation optimization schemes in different regions have been proposed,and the evacuation of each group before and after optimization is simulated in Anylogic.Comparison Analysis of the evacuation data before and after optimization,the speed change of the scattering of the table and the staircase area is more stable,the density of the population of the steering area has decreased,and the evacuation efficiency of the corridor area has increased by 1.74% to 55%,which proves the effectiveness of the evacuation optimization scheme.Survey of safe evacuation of venues is proposed according to the venue evacuation bottleneck and optimization.The research adopts the method of actual evacuation data extraction and simulation simulation,with the research-based research on the evacuation of people,and has improved innovation for social power models,and proposed a venue evacuation optimization program and suggestions.Research provides a reference...
